Preheat oven to 400°F. Generously grease a 1.5-quart casserole dish with nonstick cooking spray. Set aside.
In a large sauté pan, heat the olive oil and butter over medium heat. Lower heat to low, add the onions and sprinkle with ⅛-teaspoon salt; cook, stirring frequently, for 45 minutes to 1 hour to caramelize them. Add ½ tablespoon of thyme and garlic about halfway through caramelizing process. When the onions are done, pour them into a fine mesh sieve to drain the oil-butter sauce into a small bowl; set aside.
In a small mixing bowl, combine the remaining thyme, dried sage, black pepper and remaining salt. Spread a layer of potatoes on the bottom of the prepared baking dish, followed by a layer of caramelized onions. Sprinkle with the herb mixture. Continue layering, ending with a layer of potatoes.
Pour the vegetable stock over the top of the potato casserole, followed by the reserved oil-butter sauce. Bake for 50 to 60 minutes, until the top is golden brown and the potatoes are crispy around the edges. Allow to rest for 15 minutes. Serve warm and enjoy!
